Cable ladder:

Commonly known as: ladder tray, cable runway.A cable ladder has a range of straight lengths and different shaped fittings designed to facilitate changing cabling directions or levels easily, without the need to modify any components. Ladders are considered to be the strongest products that are available to support cables, offering high load capabilities over long spans, and thus are often to be installed on sites where the need to distribute high volumes of cables safely, reliably and quickly is of paramount importance to the project managers.

● Has a simple design of side rails with rungs connected? The rungs are perforated, which makes it easy to fasten cable ties or cable cleats directly onto the ladder.

● It is of stronger build. Configuration is easy.

● Air circulation is free hence derating of cable current carrying capacity is not required.

● Less accessories are required.

● Can carry more load

● Cable ladders are used in industrial spaces or in the basements etc, which are not public areas.

● Suited for electrical, instrumentation and telecommunications cables

● Supports heavy cables, cable bundles and pipes at long support spans

● Cables can enter and exit anywhere through the span.

● Ladders give free air flow, which is essential to avoid overheating of cables

● Minimal accumulation of water, moisture or dust

● Cables are easily accessible – making inspection and future modifications uncomplicated.

● Covers can also be added to protect cabling against UV rays, snowfall and vandalism.

● Liming Electricals’ fittings such as elbows, tee pieces, cross pieces and risers make it easy to change direction or level of the cable ladder span. These solutions require minimal space.

 

Cable tray:

Commonly known as: trough, ventilated cable tray.Cable tray is used for project planning: It is much easier to lay new cables onto a tray system as the needs of a project changes over time, rather than have to pull them through a prior installed length of conduit pipe. Hutaib Electricals manufactures and supplies light duty perforated cable tray and duct, through to medium and heavy duty ‘ladder tray’ type products that rival the load bearing capacities of some cable ladders.

Cable trays are although perforated up to 70%, but air flow is not as free as in the cable ladders  hence the derating factor has to apply for the cables current carrying capacity. Cable trays are mechanically safer than in the cable ladder

● Cable trays are aesthetic and are used in public areas.

● Cable trays are available in different colours to match with the building fabric

● Cable Tray has a single sheet of metal. Many cable trays have slot patterns, which makes it easy to position equipment and fasten cable ties and other fixings.

● Suitable for light electrical and instrumentation cables and tubing.

● The bottom coverage reduces electromagnetic interference, and the perforations enable water drainage and ventilation.

● Trays provide additional support and prevent cables from drooping, which could potentially damage the circuit’s performance.

● Cable trays are the most aesthetically pleasing option. In buildings with no panelled ceiling, cable trays can be a great option for hiding cables whilst keeping them organised.

● Covers can be added to protect cabling against UV, snow/ice and vandalism.

Both are cable containments. But there is a difference.
